Ocean's Origin

Ocean's Origin is a cave located on Route 17, and is thought to be the dwelling of a great beast. After entering the cave, you must go through a small tunnel with one pillar of rock sideways. After exiting the tunnel, you will find a small pool of water and a pedestal upon a pattern on the floor. If you turn left after exiting the tunnel, find a wall of rock and tucked behind it you will find TM 70. It also seems to have a blue glow all around the cave.

Pedestal
At the end of the cave, in front of a large pool of water, there is a blue pedestal. A closer look shows some markings and the same markings are found under the pedestal on the ground. It also seems something should be placed on the pedestal... but what could it be?
